Why per-database-connection request

[mivinci]

It seems that apps/api creates a new database connection for each request, according to https://github.com/unkeyed/unkey/blob/main/apps/api/src/pkg/middleware/init.ts.

I know that a global connection instance is not allowed outside the entry of Cloudflare workers, but have no idea why we can live with that.

More than just Unkey, I've seen a lot of code snippets showing such an approach on other serverless JS runtimes.

Can somebody please explain?

We connect to the database via http, there is no long living connection like in traditional tcp based database connections.

Okay it looks like using an HTTP client for each request has gone mainstream in the serverless world since allocating memory for an HTTP client is relatively acceptable. Thanks for your help )
